Re: Info about Flow deck and Loco position

Secondly, about your question with the LPS system together of the flow-deck. They should work together, as long if you are flying as low as the bottom range sensor still can measure something. But it might be good to keep an eye on this github issue, which is discussing the same thing https://githu...

Re: Info about Flow deck and Loco position

The LPS system is not able to read the heading of the ...

Info about Kalman filter

HEllo, i have one question. Does the Kalman filter works on the firmware even without the LPS and only the flow deck is connected? Or there is another estimator running when LPS is not available? I'm asking this because on Raffaello D'Andrea's paper is clearly written: "The estimator presented in Se...
